一、建按月自增分区表：
1.1建表
SQL> create table month_interval_partition_table (id number,time_col date) partition by range(time_col)
2 interval (numtoyminterval(1,'month'))
3 (
4 partition p_month_1 values less than (to_date('2014-01-01','yyyy-mm-dd'))
5 );
Table created
1.2 查看现在分区
SQL> select table_name,partition_name from user_tab_partitions where table_name='MONTH_INTERVAL_PARTITION_TABLE';
1.3、插入数据
SQL> begin
2 for i in 0..11 loop
3 insert into MONTH_INTERVAL_PARTITION_TABLE values(i,add_months(to_date('2014-01-01','yyyy-mm-dd'),i));
4 end loop;
5 commit;
6 end;
7 /
PL/SQL procedure successfully completed
SQL> select table_name,partition_name from user_tab_partitions where table_name='MONTH_INTERVAL_PARTITION_TABLE';
神通kstore数据库查看分区表
select * From V_SYS_TAB_PARTITIONS
1.5查看其中一个分区数据
SQL> select * From MONTH_INTERVAL_PARTITION_TABLE partition(SYS_P22);
二、创建按天的分区表
2.1建表
SQL> create table day_interval_partition_table (id number,time_col date) partition by range(time_col)
2 interval (numtodsinterval(1,'day'))
3 (
4 partition p_day_1 values less than (to_date('2014-01-01','yyyy-mm-dd'))
5 );
Table created
2.2、查看现在分区
SQL> select table_name,partition_name from user_tab_partitions where table_name='DAY_INTERVAL_PARTITION_TABLE';
TABLE_NAME PARTITION_NAME
------------------------------ ------------------------------
DAY_INTERVAL_PARTITION_TABLE P_DAY_1
2.3、插入数据
SQL> begin
2 for i in 1..12 loop
3 insert into DAY_INTERVAL_PARTITION_TABLE values(i,trunc(to_date('2014-01-01','yyyy-mm-dd')+i));
4 end loop;
5 commit;
6 end;
7 /
PL/SQL procedure successfully completed
2.4查看分区
SQL> select table_name,partition_name from user_tab_partitions where table_name='DAY_INTERVAL_PARTITION_TABLE';
2.5查看数据
SQL> select table_name,partition_name from user_tab_partitions where table_name='DAY_INTERVAL_PARTITION_TABLE';
查看某个分区数据
select * From DAY_INTERVAL_PARTITION_TABLE partition(SYS_P39);
